1. A display panel comprising:

  • an array substrate and a color filter substrate which are arranged opposite to each other;

    a liquid crystal layer arranged between the array substrate and the color filter substrate;

    an upper polarizing layer provided between the color filter substrate and the liquid crystal layer;

    a quantum dot excitation layer provided on the color substrate, anda plurality of black matrices provided between the quantum dot excitation layer and the color filter substrate,wherein the upper polarizing layer is configured such that a first linearly polarized light transmitted through the upper polarizing layer irradiates on the quantum dot excitation layer,wherein the quantum dot excitation layer comprises a red quantum dot film corresponding to a red sub-pixel, a green quantum dot film corresponding to a green sub-pixel and a transparent film corresponding to a blue sub-pixel, which are alternately arranged, a first blue filter layer is provided between the red quantum dot film and the color filter substrate, and a second blue filter layer is provided between the green quantum dot film and the color filter substrate, andwherein the black matrices are provided between the first blue filter layer and the second blue filter layer, and at the ends of the first blue filter layer and the second blue filter layer facing away from each other, respectively.
